Abstract: PURPOSE:To prevent a malfunction due to the uncertain receiver output of the reception side by providing an open collector type gate circuit and transmitting the output signal of said gate circuit via a cable that transmits the balance type digital signals to perform the control for closure of the receiver output. CONSTITUTION:The voltage obtained by dividing the power supply voltage +5V by resistances 14 and 15 is applied to the base of a transistor TR16 in the form of the base bias voltage. The emitter of the TR16 is grounded together with the collector connected to a reverse gate 10 of a device B at the reception side via a connector 4, a cable 5 and a connector 6. Thus the voltage +5V of the device B is applied via a resistance 9. When the power supply of a device A is cut off, a gate circuit 13 has no actuation. Then the output terminal of an inactive open collector type gate circuit is opened. Therefore, the logic level is set at ''1'' and accordingly the output signal of the gate 10 is set at ''0''. Thus an AND gate 11 is closed and the output of a receiver 8 is closed.

Abstract: PURPOSE:To turn on and off a large-capacity switching transistor (TR) at high speed, by applying a plus voltage to the collector of one TR and a minus voltage to the collector of the other TR, and connecting the base of a control TR to their common emitter. CONSTITUTION:When an input signal is applied between terminals 5 and 6, a light emitting diode 7 turns on to turn on a photoresist TR8.

Abstract: PURPOSE:To kill ticks and minute insects by the use of a usual paper bag filter without requiring any particular operation by disposing an impeller driven by a motor in a sucking passage, and forming a high temperature atmosphere around the impeller or giving toxicity to the impeller surface. CONSTITUTION:A tick killing device 11 is installed in the middle of a pipe 5. When the switch of a cleaner is operated, a motor 18 is started together with a blower in a body. Consequently, an air flow 20a running in the axial direction of the pipe in the sucking passage forms an air flow 20b running in centrifugal direction by a rotating impeller 19, which air flow blows the air onto the inner circumferential surface 13a of a casing. As the impeller 19 is provided with a heater 21, the impeller surface and its circumference becomes a high temperature atmosphere of 50 deg.C or more, and the ticks surviving the shock are killed by the high temperature. The impeller surface has a coat of an insecticide such as hinoki oil or is impregnated with it, and the surface is toxic. Therefore, the ticks never killed by the mechanical shock are killed by the toxicity of the impeller surface.

Abstract: PURPOSE:To reduce the distortion of signal due to the AGC operation and operate AGC in a low level by distinguishing the sound presence state and the no-sound state of an audio signal from each other with one threshold level and operating the AGC only in case of the sound presence state. CONSTITUTION:The lowest level in an input signal range handled by AGC is set as an initial threshold to a threshold register 22 by an initial value setting circuit 21 of a threshold control part 2. In the first state, a discrimination output (f) of a level comparing and discriminating circuit A indicates the no-sound state. A selector 24 selects an input d2 in case of the no-signal state and selects an input d1 in case of the sound presence state in accordance with the output (f). If an input audio signal Ein higher than a threshold Eth comes, the output (f) of the level comparing and discriminating circuit 20 indicates that the sound is in a state of presence, and the input d1 is selected by the selector 24. The input d1 corrects the threshold with a value obtained by multiplying a gain correction quantity DELTAG of ACG by a certain weighing coefficient beta in a multiplier (a). Consequently, the no-sound state is discriminated in a relatively high level, and the fall of the signal is detected quickly.
